<p>A method of detecting a jamming signal ( 304 ) in a wireless device ( 102 ) includes providing a plurality of channels ( 401 ), wherein each of the plurality of channels has an NCO frequency ( 428, 429 ), and receiving a channel lock indicator ( 430, 431 ) for each of the plurality of channels. A jamming signal is detected if the NCO frequency of each of the plurality of channels differs by an integer multiple of an inverse of a pseudorandom noise code period ( 424, 425 ). A wireless device includes a plurality of channels, wherein each of the plurality of channels has an NCO frequency. A frequency tracking loop for each of the plurality of channels outputs a channel lock indicator for each of the plurality of channels. A jamming detection module receives the channel lock indicator and the NCO frequency from each of the plurality of channels. The jamming detection module detects an interference condition if the NCO frequency of each of the plurality of channels differs by an integer multiple of an inverse of a pseudorandom noise code period.</p> |
